try to find two numbers that multiply to get that number. if you cant try to get something close to the same. then if one is an even number just divide it by 2 and multiply the other number by 2. keep doing this until you cant divide the number anymore. that should get you most of the factors
128 = 27. You can find out this sort of things quickly if you take the trouble to divide the number into prime factors.
You can quickly find the factors for even numbers 50 to 100 by dividing each number by all possible factors (starting from 2) until reaching the square root of the number. If a number is divisible without a remainder, then it is a factor of that even number. Repeat this process for each even number between 50 and 100.

You can quickly find factors of reasonably-sized numbers at Wolfram Alpha. Just type "factor" followed by the number, in the input box. If you want to find out HOW to get all those factors, ask the corresponding question here.
You can quickly find the factors for even numbers 50 to 100 by dividing each number by all possible factors (starting from 2) until reaching the square root of the number. If a number is divisible without a remainder, then it is a factor of that even number. Repeat this process for each even number between 50 and 100.
The principal factors are temperature and pressure.
By rounding the factors, then quickly multiplying them in your head.

The factors of 100 are included in the factors of 200, but I did not use one to find the other.

Multiplication factors cannot be used to find divination factors.
Evaluate is to find the value of powers by multiplying the factors.
Once you have the prime factorization, it is much easier to find the factors, the proper factors, the GCF and LCM.
